+# SolidCraft — instructions for agents
 
-SolidCraft is a clean-room, pure-Rust parametric 3D CAD app (sketch solver, feature timeline, B-rep kernel, an egui UI that agents drive). This file is a router: the hard rules, then the skill to read for your task. Humans: CONTRIBUTING.md.
+SolidCraft is a clean-room, open-source, pure-Rust parametric 3D CAD application:
+sketches with a constraint solver, a parametric timeline of features, a B-rep
+kernel, and a desktop UI that agents can drive. Projects published by
+[storytold](https://github.com/storytold) can serve as references for implementation conventions.
+Any code adapted from other projects (MIT OR Apache-2.0) is noted in ATTRIBUTION.md.
 
-## Start here
-Work: ROADMAP.md, "Where help is wanted most" in CONTRIBUTING.md, issues labelled `help wanted`, `good first issue`, `needs-triage`; architecture in `docs/architecture.md`. Act when the code, docs and rules settle a question; ask only when it changes what users see. Local `plan/` notes are optional.
+## Product name
+SolidCraft everywhere: crates `solidcraft-*`, binaries `solidcraft` and `solidcraft-cli`,
+`.solidcraft` designs, the `solidcraft/N` format tag, `SOLIDCRAFT_*` environment variables,
+settings and recovery folders, the MCP server name, docs, CI and packaging. The old name
+survives only in the explicit compatibility shims listed in `docs/compatibility.md`; don't add
+new uses of it anywhere else. Public docs/web/Flatpak deployments use project Pages
+`/solidcraft/`; do not add permanent old-name Pages aliases.
 
-## Hard rules (what enforces each)
-- Independent: never copy another product's code, icons, text or templates; never drive or take data from commercial CAD. `skills/solidcraft-ground-rules/SKILL.md`.
-- No GPL/LGPL/AGPL code, not even reading it (OpenCASCADE, FreeCAD, SolveSpace, CadQuery, LibreCAD, QCAD): `cargo xtask licences --check`.
-- Every asset is original or openly licensed with a row in ATTRIBUTION.md; read `assets/AGENTS.md` before icon work: `cargo xtask assets`, `cargo xtask icons`.
-- Never crash: no unwrap/expect/panic/unsafe in non-test code (unsafe allowlist in crash-safety), errors are `Result`, input is hostile: clippy `-D warnings`, `hostile_params_never_panic`.
-- Everything is a command and programmatic calls never open dialogs: `skills/solidcraft-commands/SKILL.md`.
-- Layering (geom, sketch/kernel/render, doc, io, engine, ui-egui, apps); only `crates/kernel` uses truck: `cargo xtask layers`.
-- One outer UI container, one camera path (`navigation::handle`), colours from theme tokens: `cargo xtask ui-containers`.
-- Application code is Rust only and builds for wasm: `cargo xtask wasm`, `cargo xtask web-offline-test`.
-- The product name is SolidCraft; the old name lives only in `docs/compatibility.md`.
-- Sorted lists (message catalogs, `mod` lines, languages) stay sorted: `cargo xtask lists`. Never edit generated files (`docs/features.md`, `THIRD-PARTY-LICENSES.txt`) in a PR.
-- A design-format change is ONE new file in `crates/doc/src/format/pending/`: `scripts/test-format-pending.sh`.
-- A command has input and output schemas (will become required; `schema/unconverted.txt` only shrinks): `skills/solidcraft-commands/SKILL.md`.
-- New UI strings go in `assets/locales/pending/<slug>.json`, ATTRIBUTION rows in `attribution/pending/<slug>.md`: `cargo xtask lists`.
-- A changed default keeps the old behaviour behind a preference and fills the PR's `Changes a default:` line, and no second PR for an issue a lower-numbered one closes: `pr-checks.yml`.
-- A regression test goes in the area's existing test file, never a per-bug file (#3226).
-- Look at open PRs first, claim with a draft PR (lowest number wins), one topic per PR, never force-push `main`, no pushes just to catch up with `main`: `skills/solidcraft-contributing/SKILL.md`.
-- Show observable changes with real screenshots or a recording, captured yourself.
-- Run `cargo xtask ci` before every commit, without switching branches while it runs. `cargo xtask skills` keeps this file and `skills/` honest.
+## Start every session here
+1. Read `plan/STATUS.md` (current milestone, next task), then the task in `plan/execution-plan.md`
+   and the relevant `plan/architecture.md` section.
+2. Kernel and library decisions: `plan/adr/0001-geometry-kernel.md` (what we may depend on, what
+   is rejected for licence reasons).
+3. Follow the autonomous operation protocol (`plan/execution-plan.md` §6). Don't stop to ask
+   unless it lists the decision as the owner's.

+## Never crash
+People trust SolidCraft with their designs; a crash loses their work. **This outranks feature work.**
+- **No panics in non-test code:** no `unwrap()`, `expect()`, `panic!`, `unreachable!`, `todo!`,
+  `unimplemented!`; no `unsafe` (`unsafe_code = "forbid"`). The three exceptions, in the app crate
+  (which denies it instead), have no safe API: two functions in
+  `apps/solidcraft/src/open_documents.rs` (macOS hands Finder files only to an Objective-C
+  method), the Windows-only `apps/solidcraft/src/native_crash.rs` (the exception filter that
+  records crashes inside native code such as graphics drivers) and the Windows-only
+  `apps/solidcraft/src/native_frame.rs` (the window procedure that answers the resize-border hit
+  test of the window without OS decorations).
+- **Errors are `Result<T, E>`** through the crate's error type and `?`. An unfinished feature
+  returns an error ("not supported yet: …"); it never panics.
+- **Input-derived numbers are hostile** (command parameters, design files, control-channel
+  input): `get()` not `[i]`, finite checks, caps on sizes and loop counts.
+- **Third-party kernel calls are guarded:** everything that calls `truck` goes through
+  `solidcraft_kernel::guard`, which turns a panic into `KernelError::Internal`.
+- **Last-resort guard:** `Session::execute` runs every command under `catch_unwind`; an escaped
+  panic restores the design and reports `EngineError::Internal`.
+- **Crash reports:** the desktop app writes every panic and every unclean exit to a local crash folder,
+  with the design and the commands that reproduce it (`solidcraft_engine::crash`, docs/crash-reports.md).
+  When someone says the app crashed, look there first: `solidcraft-cli crashes`, `crashes show <id>`,
+  `crashes replay <id>` (or the `diagnostics.crash_reports` command / MCP `crash_reports` tool).
+- **Prove it:** every crash fix lands with a regression test (see `hostile_params_never_panic`); a
+  crash report's `design.solidcraft` + `replay.json` is the test's starting point.
+- Every production crate root carries
+  `#![deny(clippy::unwrap_used, clippy::expect_used, clippy::panic, clippy::unimplemented, clippy::todo, clippy::unreachable)]`.
+
+## Non-negotiables
+- **Independent.** SolidCraft is independent. Behaviour is designed from public documentation,
+  general CAD conventions and user feedback. Reference tests use analytic values and open-source
+  tools. Never copy another product's code, icons, artwork, help text, tooltips, templates or
+  materials. File formats come from public specifications.
+- **No commercial CAD products.** Agents must not drive, script, automate or extract data from
+  commercial CAD products (Fusion, SolidWorks, Onshape, …) for this project: no test data,
+  measurements, command lists, ids or files produced with them.
+- **Never read, copy or link GPL/LGPL/AGPL code**: OpenCASCADE, FreeCAD (incl. planegcs),
+  SolveSpace, CadQuery/OCP, LibreCAD, QCAD — don't even read their sources. (`tools/freecad-oracle/`
+  runs FreeCAD as a separate program through its public scripting API to compute reference values;
+  nothing from FreeCAD is linked, vendored or shipped.) The sketch solver and the blend
+  operations are our own.
+- **Assets — absolutely essential.** SolidCraft contains **no iconography, images, fonts or
+  artwork from commercial CAD products — ever.** Command icons are the original SVG masters in
+  `assets/icons/ui/design/svg/`, compiled through `crates/ui-egui/src/icon_svg.rs`.
+  **Before any icon, icon assignment or media edit, read `assets/AGENTS.md`,
+  `assets/icons/ui/AGENTS.md` and `assets/icons/ui/STYLE_GUIDE.md`.** Use the canonical
+  bases and named finished references there; never invent a parallel icon style. Any file asset must be original or openly licensed and **must have a row in ATTRIBUTION.md**
+  (`cargo xtask assets` enforces it). Screenshots of commercial CAD software are never committed.
+  Breaking this rule is the most serious mistake you can make in this repo.
+- **Everything is a command.** User-visible behaviour = a command in `crates/engine/src/cmd/*`
+  (`CommandSpec`: id = our own dotted, lower-case id `<area>.<thing>[.<variant>]` such as
+  `solid.extrude` or `sketch.rectangle.two_point`, never another product's command id; label;
+  toolbar tab and panel; icon; shortcut; params doc; `enabled`; JSON `run`) + tests. The toolbar,
+  dialogs, sketch tools, palette, scripts, CLI and control channel all reach the same commands.
+- **Programmatic calls never open dialogs.** `engine.execute` runs the JSON form; only toolbar
+  clicks (`ui.start`) start interactive tools and dialogs, which then run commands.
+- **Layering** is enforced by `cargo xtask layers`: L0 `geom` → L1 `sketch`, `kernel`, `render`
+  → L2 `doc` → L3 `io` → L4 `engine` → L5 `ui-egui` → apps. Nothing below L5 depends on
+  egui/eframe/winit/wgpu/rfd. **The UI crate is swappable.** Only `crates/kernel` may use `truck`.
+- **The UI is thin**: panels read engine state and act through `app.run(id, params)` /
+  `app.start(id)`. Colours come from `theme::Tokens`.
+- **One set of camera controls**: every page or canvas with a camera (viewport, Render
+  preview, future flat pattern or drawing pages) calls `navigation::handle` with its `NavCaps`
+  (orbit off for flat 2D pages). New canvases must use `navigation::handle`; never hand-roll
+  camera input (a test rejects it).
+- **Application code is Rust only.** Units are millimetres and radians internally; Z is up.
+  Local asset authoring, lint and review tools use Python 3.11+ as documented in
+  `assets/AGENTS.md`; Python is not an application runtime dependency. The application exception is
+  JavaScript the browser requires: the service worker `apps/solidcraft-web/sw.js` (browsers only
+  run service workers as JavaScript) and the small inline scripts in `apps/solidcraft-web/index.html`.
+  Keep them minimal; `cargo xtask web-offline-test` covers the service worker.
+- **Quality gates** before every commit: `cargo xtask ci` (fmt, clippy -D warnings, tests,
+  assets, layers). Commit after every feature arc that builds.
+- **Publishing**: `origin` is github.com/bherbruck/solidcraft. Changes land through **pull requests**:
+  push a branch, open a PR, and let GitHub CI run. Maintainers (and agents working for them) may
+  merge their own PR as soon as CI is green (`gh pr merge --squash`); a trivial fix (docs, typos)
+  may be merged right away. Keep each PR to one topic, rebase or merge `main` into it when it
+  conflicts, and never force-push `main`. Never commit `plan/`, build dirs (`target*/`) or
+  generated reference data; check `git ls-files` before pushing.
+- **Never break wasm**: everything below the apps must build for `wasm32-unknown-unknown`
+  (`cargo xtask wasm`, part of `cargo xtask ci`).
+
+## Showing and following through on changes
+
+- Help reviewers see what is broken or changed. For observable CAD, UI or model behavior,
+  issues and PRs must include actual descriptive screenshots or a short recording from a
+  small reproduction. This includes kernel, geometry, assembly and backend changes whose
+  effects can be shown in the app. Coding agents should run the app and capture this evidence
+  themselves; do not ask a human for evidence the agent can produce. Show the actual failure
+  or result, preferably before and after, with brief reproduction steps, expected/actual
+  behavior and annotations that point out the relevant detail.
+- Flowcharts and Mermaid diagrams cannot substitute for screenshots or recordings of visible
+  behavior. Use diagrams for architectural reasoning when actual screenshots cannot illustrate
+  the point. Changes with no useful observable behavior do not need screenshot or video evidence.
+- Use a small public-safe example and check for private designs, paths, account details or
+  other sensitive content before sharing. Attach media to the issue/PR or link to an accessible
+  recording; do not commit generated screenshots or videos just to provide review evidence.
+- Throughout the work and before handoff, check current upstream commits and the relevant
+  PR's merge status. Keep your branch current with upstream merges, resolve conflicts without
+  discarding others' work, and re-run validation when integration changes the result. Use
+  `git pull --rebase origin main` before pushing as above; never force-push. Report the checked
+  upstream/PR state, any conflicts resolved and the validation performed. If a PR remains open,
+  keep monitoring it while the task is active and make its pending status clear at handoff;
+  do not claim it merged without checking.
+
+## Claim = a draft PR
+- Before working on issue #N, check nobody has it: `gh pr list -R bherbruck/solidcraft --state open --search "#N"`.
+- If none, branch from the latest `origin/main`, `git commit --allow-empty -m "claim: #N"`, push,
+  and open a **draft** PR titled `<summary> (#N)` right away. **The lowest-numbered open PR for an
+  issue wins**; if yours lost, close it. A comment or file edit alone does not replace the draft PR.
+- After opening the draft PR, comment `/claim` on the issue so the bot records the claimant and
+  adds the `in progress` label. **Do both:** the draft PR establishes ownership and `/claim` marks
+  the issue as taken. Reference `#N` in the PR so the bot can find it.
+- Push work in progress at least daily. A draft with no pushes for 72 hours may be taken over:
+  comment on it first, then open your own claim (you may start from its branch).
+  This takeover policy is separate from the bot's automatic cleanup deadlines in CONTRIBUTING.md.
+- On a shared build machine, check the load before a big build (`cut -d' ' -f1 /proc/loadavg`)
+  and wait while it is over 24; build with `nice`.
+
+## Design file format
+A change that saves something new in a design adds ONE file, `crates/doc/src/format/pending/<name>.rs`
+(a `//!` note, and `pub fn step` if older designs must be rewritten). Never edit `FORMAT`,
+`JSON_STEPS`, the history in `format.rs`, another change's file or a `v<N>/` folder: the build
+works out the number (the next one while anything is pending), and the release folds pending
+changes into `v<N>/` with `scripts/fold-format-pending.sh`. See CONTRIBUTING.md.
+
+## Application releases
+Development pushes are not application releases. Follow `docs/releasing.md` when asked to
+prepare or ship a release: choose the version from the actual changes, update Cargo.toml and
+Cargo.lock, pass the quality gates, advance `release` without force-pushing, and verify the
+resulting draft and its artifacts. When shipping is authorized, publish that verified draft
+and confirm its tag and downstream deployment. Do not auto-release every push to `main`, infer
+version bumps solely from commit prefixes, overwrite published versions, or push release tags
+before the draft is verified.
+
+## Running and looking at the app
+- `cargo run --release -p solidcraft -- --sample --control PORT` (sample design + control channel).
+  Pick a free port. Without a display, run it under `Xvfb :99` with `DISPLAY=:99`.
+- Drive it with JSON lines on `127.0.0.1:PORT` (see `docs/control-protocol.md`). The first
+  request on a connection carries the launch's token as `"token"`: read it from
+  `~/.local/share/solidcraft/control/PORT.token`, or start the app with
+  `SOLIDCRAFT_CONTROL_TOKEN=$(openssl rand -hex 32)` and send that.
+  - `{"id":1,"method":"engine.execute","params":{"command":"solid.extrude","params":{"distance":20}}}`
+  - `{"id":2,"method":"ui.start","params":{"command":"sketch.create"}}` then `ui.click {x, y}`
+  - `{"id":3,"method":"ui.screenshot","params":{"path":"/tmp/shot.png"}}` then read the PNG.
+- **For UI work, look at the result** (screenshot, read the PNG). Without a window use
+  `ui.render` or `solidcraft-cli snapshot`.
+- Headless: `solidcraft-cli run script.json --out part.step`, `solidcraft-cli eval design.solidcraft`,
+  `solidcraft-cli snapshot script.json --out shot.png`, `solidcraft-cli commands`.
+- Reference tests: `cargo xtask oracle` replays `tests/oracle/*/recipe.json` and compares with
+  each case's `expected.json` (analytic or FreeCAD values; writes `docs/oracle.md`). Expected
+  values never come from a commercial CAD product.
+- Build with `CARGO_TARGET_DIR=<repo>/target`. Windows: `cargo xwin build --release --target x86_64-pc-windows-msvc -p solidcraft`.
+
+## Roadmap
+`ROADMAP.md` (committed) tracks status, milestones and estimates. Update it whenever a
+milestone task lands. `docs/features.md` (SolidCraft's commands by area, from the registry) and
+`THIRD-PARTY-LICENSES.txt` are regenerated on `main` after each merge by the Generated files
+workflow; never regenerate them in a PR.
+
+## Lists many PRs add to
+Keep them conflict-free (CONTRIBUTING.md, "Lists many changes add to"): message catalogs sorted
+(`cargo xtask lists --fix`), `mod` lines in their sorted group, the language list English first
+then by id, generated files left to `main`, and a design-format change as one new file.

-### Built-in render resource adapters (personal integration batch, 2026-10-22)
-
-The original adapters in `crates/engine/src/cmd/render/library.rs`, the generated lookup `library_data.rs` and its generator `tools/render-library/generate.py` project the already attributed starter and SELENE resources without replacing their bytes or authoring manifests. The added scalar texture channels, explicit color/V conventions and immutable-source/GPU-payload sharing are original contributor work under MIT OR Apache-2.0. No external code, commercial CAD data or new third-party imagery was imported. Source metadata and the original authoring attribution remain authoritative; pending runtime acceptance is not a photometric or engineering qualification.

+# SolidCraft — instructions for agents
 
-The agent instructions for this repo live in AGENTS.md; edit that file only.
+SolidCraft is a clean-room, open-source, pure-Rust parametric 3D CAD application:
+sketches with a constraint solver, a parametric timeline of features, a B-rep
+kernel, and a desktop UI that agents can drive. Projects published by
+[storytold](https://github.com/storytold) can serve as references for implementation conventions.
+Any code adapted from other projects (MIT OR Apache-2.0) is noted in ATTRIBUTION.md.
+
+## Product name
+SolidCraft everywhere: crates `solidcraft-*`, binaries `solidcraft` and `solidcraft-cli`,
+`.solidcraft` designs, the `solidcraft/N` format tag, `SOLIDCRAFT_*` environment variables,
+settings and recovery folders, the MCP server name, docs, CI and packaging. The old name
+survives only in the explicit compatibility shims listed in `docs/compatibility.md`; don't add
+new uses of it anywhere else. Public docs/web/Flatpak deployments use project Pages
+`/solidcraft/`; do not add permanent old-name Pages aliases.
+
+## Start every session here
+1. Read `plan/STATUS.md` (current milestone, next task), then the task in `plan/execution-plan.md`
+   and the relevant `plan/architecture.md` section.
+2. Kernel and library decisions: `plan/adr/0001-geometry-kernel.md` (what we may depend on, what
+   is rejected for licence reasons).
+3. Follow the autonomous operation protocol (`plan/execution-plan.md` §6). Don't stop to ask
+   unless it lists the decision as the owner's.
+
+`plan/` is gitignored (local only).
+
+## Never crash
+People trust SolidCraft with their designs; a crash loses their work. **This outranks feature work.**
+- **No panics in non-test code:** no `unwrap()`, `expect()`, `panic!`, `unreachable!`, `todo!`,
+  `unimplemented!`; no `unsafe` (`unsafe_code = "forbid"`). The exceptions, in the app crate and in
+  `crates/threedx-client` (which deny it instead), have no safe API: the macOS-only
+  `crates/threedx-client/src/macos.rs` (loads the 3Dconnexion driver's client framework at run time
+  and calls through its function pointers), two functions in
+  `apps/solidcraft/src/open_documents.rs` (macOS hands Finder files only to an Objective-C
+  method), the Windows-only `apps/solidcraft/src/native_crash.rs` (the exception filter that
+  records crashes inside native code such as graphics drivers) and the Windows-only
+  `apps/solidcraft/src/native_frame.rs` (the window procedure that answers the resize-border hit
+  test of the window without OS decorations).
+- **Errors are `Result<T, E>`** through the crate's error type and `?`. An unfinished feature
+  returns an error ("not supported yet: …"); it never panics.
+- **Input-derived numbers are hostile** (command parameters, design files, control-channel
+  input): `get()` not `[i]`, finite checks, caps on sizes and loop counts.
+- **Third-party kernel calls are guarded:** everything that calls `truck` goes through
+  `solidcraft_kernel::guard`, which turns a panic into `KernelError::Internal`.
+- **Last-resort guard:** `Session::execute` runs every command under `catch_unwind`; an escaped
+  panic restores the design and reports `EngineError::Internal`.
+- **Crash reports:** the desktop app writes every panic and every unclean exit to a local crash folder,
+  with the design and the commands that reproduce it (`solidcraft_engine::crash`, docs/crash-reports.md).
+  When someone says the app crashed, look there first: `solidcraft-cli crashes`, `crashes show <id>`,
+  `crashes replay <id>` (or the `diagnostics.crash_reports` command / MCP `crash_reports` tool).
+- **Prove it:** every crash fix lands with a regression test (see `hostile_params_never_panic`); a
+  crash report's `design.solidcraft` + `replay.json` is the test's starting point.
+- Every production crate root carries
+  `#![deny(clippy::unwrap_used, clippy::expect_used, clippy::panic, clippy::unimplemented, clippy::todo, clippy::unreachable)]`.
+
+## Non-negotiables
+- **Independent.** SolidCraft is independent. Behaviour is designed from public documentation,
+  general CAD conventions and user feedback. Reference tests use analytic values and open-source
+  tools. Never copy another product's code, icons, artwork, help text, tooltips, templates or
+  materials. File formats come from public specifications.
+- **No commercial CAD products.** Agents must not drive, script, automate or extract data from
+  commercial CAD products (Fusion, SolidWorks, Onshape, …) for this project: no test data,
+  measurements, command lists, ids or files produced with them.
+- **Never read, copy or link GPL/LGPL/AGPL code**: OpenCASCADE, FreeCAD (incl. planegcs),
+  SolveSpace, CadQuery/OCP, LibreCAD, QCAD — don't even read their sources. (`tools/freecad-oracle/`
+  runs FreeCAD as a separate program through its public scripting API to compute reference values;
+  nothing from FreeCAD is linked, vendored or shipped.) The sketch solver and the blend
+  operations are our own.
+- **Assets — absolutely essential.** SolidCraft contains **no iconography, images, fonts or
+  artwork from commercial CAD products — ever.** Every UI icon is drawn in collected code
+  (`assets/icons/ui/source/`, compiled through `crates/ui-egui/src/icons.rs`). Any file asset must be original or openly licensed and **must have a row in ATTRIBUTION.md**
+  (`cargo xtask assets` enforces it). Screenshots of commercial CAD software are never committed.
+  Breaking this rule is the most serious mistake you can make in this repo.
+- **Everything is a command.** User-visible behaviour = a command in `crates/engine/src/cmd/*`
+  (`CommandSpec`: id = our own dotted, lower-case id `<area>.<thing>[.<variant>]` such as
+  `solid.extrude` or `sketch.rectangle.two_point`, never another product's command id; label;
+  toolbar tab and panel; icon; shortcut; params doc; `enabled`; JSON `run`) + tests. The toolbar,
+  dialogs, sketch tools, palette, scripts, CLI and control channel all reach the same commands.
+- **Programmatic calls never open dialogs.** `engine.execute` runs the JSON form; only toolbar
+  clicks (`ui.start`) start interactive tools and dialogs, which then run commands.
+- **Layering** is enforced by `cargo xtask layers`: L0 `geom` → L1 `sketch`, `kernel`, `render`
+  → L2 `doc` → L3 `io` → L4 `engine` → L5 `ui-egui` → apps. Nothing below L5 depends on
+  egui/eframe/winit/wgpu/rfd. **The UI crate is swappable.** Only `crates/kernel` may use `truck`.
+- **The UI is thin**: panels read engine state and act through `app.run(id, params)` /
+  `app.start(id)`. Colours come from `theme::Tokens`.
+- **One set of camera controls**: every page or canvas with a camera (viewport, Render
+  preview, future flat pattern or drawing pages) calls `navigation::handle` with its `NavCaps`
+  (orbit off for flat 2D pages). New canvases must use `navigation::handle`; never hand-roll
+  camera input (a test rejects it).
+- **Rust only.** Units are millimetres and radians internally; Z is up. The one exception is
+  JavaScript the browser requires: the service worker `apps/solidcraft-web/sw.js` (browsers only
+  run service workers as JavaScript) and the small inline scripts in `apps/solidcraft-web/index.html`.
+  Keep them minimal; `cargo xtask web-offline-test` covers the service worker.
+- **Quality gates** before every commit: `cargo xtask ci` (fmt, clippy -D warnings, tests,
+  assets, layers). Commit after every feature arc that builds.
+- **Publishing**: `origin` is github.com/bherbruck/solidcraft. Changes land through **pull requests**:
+  push a branch, open a PR, and let GitHub CI run. Maintainers (and agents working for them) may
+  merge their own PR as soon as CI is green (`gh pr merge --squash`); a trivial fix (docs, typos)
+  may be merged right away. Keep each PR to one topic, rebase or merge `main` into it when it
+  conflicts, and never force-push `main`. Never commit `plan/`, build dirs (`target*/`) or
+  generated reference data; check `git ls-files` before pushing.
+- **Never break wasm**: everything below the apps must build for `wasm32-unknown-unknown`
+  (`cargo xtask wasm`, part of `cargo xtask ci`).
+
+## Showing and following through on changes
+
+- Help reviewers see what is broken or changed. For observable CAD, UI or model behavior,
+  issues and PRs must include actual descriptive screenshots or a short recording from a
+  small reproduction. This includes kernel, geometry, assembly and backend changes whose
+  effects can be shown in the app. Coding agents should run the app and capture this evidence
+  themselves; do not ask a human for evidence the agent can produce. Show the actual failure
+  or result, preferably before and after, with brief reproduction steps, expected/actual
+  behavior and annotations that point out the relevant detail.
+- Flowcharts and Mermaid diagrams cannot substitute for screenshots or recordings of visible
+  behavior. Use diagrams for architectural reasoning when actual screenshots cannot illustrate
+  the point. Changes with no useful observable behavior do not need screenshot or video evidence.
+- Use a small public-safe example and check for private designs, paths, account details or
+  other sensitive content before sharing. Attach media to the issue/PR or link to an accessible
+  recording; do not commit generated screenshots or videos just to provide review evidence.
+- Throughout the work and before handoff, check current upstream commits and the relevant
+  PR's merge status. Keep your branch current with upstream merges, resolve conflicts without
+  discarding others' work, and re-run validation when integration changes the result. Use
+  `git pull --rebase origin main` before pushing as above; never force-push. Report the checked
+  upstream/PR state, any conflicts resolved and the validation performed. If a PR remains open,
+  keep monitoring it while the task is active and make its pending status clear at handoff;
+  do not claim it merged without checking.
+
+## Claim = a draft PR
+- Before working on issue #N, check nobody has it: `gh pr list -R bherbruck/solidcraft --state open --search "#N"`.
+- If none, branch from the latest `origin/main`, `git commit --allow-empty -m "claim: #N"`, push,
+  and open a **draft** PR titled `<summary> (#N)` right away. **The lowest-numbered open PR for an
+  issue wins**; if yours lost, close it. Opening the PR is the claim: the bot assigns you and
+  labels the issue `in progress` (or says on your PR who holds it). Don't claim by editing files.
+- Push work in progress at least daily. A draft with no pushes for 72 hours may be taken over:
+  comment on it first, then open your own claim (you may start from its branch).
+- On a shared build machine, check the load before a big build (`cut -d' ' -f1 /proc/loadavg`)
+  and wait while it is over 24; build with `nice`.
+
+## Design file format
+A change that saves something new in a design adds ONE file, `crates/doc/src/format/pending/<name>.rs`
+(a `//!` note, and `pub fn step` if older designs must be rewritten). Never edit `FORMAT`,
+`JSON_STEPS`, the history in `format.rs`, another change's file or a `v<N>/` folder: the build
+works out the number (the next one while anything is pending), and the release folds pending
+changes into `v<N>/` with `scripts/fold-format-pending.sh`. See CONTRIBUTING.md.
+
+## Application releases
+Development pushes are not application releases. Follow `docs/releasing.md` when asked to
+prepare or ship a release: choose the version from the actual changes, update Cargo.toml and
+Cargo.lock, pass the quality gates, advance `release` without force-pushing, and verify the
+resulting draft and its artifacts. When shipping is authorized, publish that verified draft
+and confirm its tag and downstream deployment. Do not auto-release every push to `main`, infer
+version bumps solely from commit prefixes, overwrite published versions, or push release tags
+before the draft is verified.
+
+## Running and looking at the app
+- `cargo run --release -p solidcraft -- --sample --control PORT` (sample design + control channel).
+  Pick a free port. Without a display, run it under `Xvfb :99` with `DISPLAY=:99`.
+- Drive it with JSON lines on `127.0.0.1:PORT` (see `docs/control-protocol.md`). The first
+  request on a connection carries the launch's token as `"token"`: read it from
+  `~/.local/share/solidcraft/control/PORT.token`, or start the app with
+  `SOLIDCRAFT_CONTROL_TOKEN=$(openssl rand -hex 32)` and send that.
+  - `{"id":1,"method":"engine.execute","params":{"command":"solid.extrude","params":{"distance":20}}}`
+  - `{"id":2,"method":"ui.start","params":{"command":"sketch.create"}}` then `ui.click {x, y}`
+  - `{"id":3,"method":"ui.screenshot","params":{"path":"/tmp/shot.png"}}` then read the PNG.
+- **For UI work, look at the result** (screenshot, read the PNG). Without a window use
+  `ui.render` or `solidcraft-cli snapshot`.
+- Headless: `solidcraft-cli run script.json --out part.step`, `solidcraft-cli eval design.solidcraft`,
+  `solidcraft-cli snapshot script.json --out shot.png`, `solidcraft-cli commands`.
+- Reference tests: `cargo xtask oracle` replays `tests/oracle/*/recipe.json` and compares with
+  each case's `expected.json` (analytic or FreeCAD values; writes `docs/oracle.md`). Expected
+  values never come from a commercial CAD product.
+- Build with `CARGO_TARGET_DIR=<repo>/target`. Windows: `cargo xwin build --release --target x86_64-pc-windows-msvc -p solidcraft`.
+
+## Roadmap
+`ROADMAP.md` (committed) tracks status, milestones and estimates. Update it whenever a
+milestone task lands. `docs/features.md` (SolidCraft's commands by area, from the registry) and
+`THIRD-PARTY-LICENSES.txt` are regenerated on `main` after each merge by the Generated files
+workflow; never regenerate them in a PR.
+
+## Lists many PRs add to
+Keep them conflict-free (CONTRIBUTING.md, "Lists many changes add to"): message catalogs sorted
+(`cargo xtask lists --fix`), `mod` lines in their sorted group, the language list English first
+then by id, generated files left to `main`, and a design-format change as one new file.

-- **Windows:** the [installer][windows-msi].
-- **macOS:** the [disk image][macos-dmg] (Apple silicon and Intel).
-- **Linux:** the [AppImage][linux-appimage], or `sudo snap install solidcraft` ([Snap Store][snap-store]).
+- **Windows:** download and run the [installer][windows-msi].
+  Also for [ARM64][windows-arm64-msi] and [32-bit][windows-x86-msi] PCs, or as a
+  [portable zip][windows-portable] that runs without installing.
+  With [WinGet](https://learn.microsoft.com/windows/package-manager/winget/):
+  `winget install bherbruck.SolidCraft`.
+- **macOS:** open the [disk image][macos-dmg] and drag SolidCraft into Applications
+  (Apple silicon and Intel).
+- **Linux:** download the [AppImage][linux-appimage], allow it to run as a program and open it.
+  Or install the [.deb][linux-deb] (Ubuntu, Debian, Mint) or [.rpm][linux-rpm] (Fedora,
+  openSUSE), or use [Flatpak](https://docs.solidcraft.io/guide/getting-started.html#linux-flatpak).
+  With Snap: `sudo snap install solidcraft` ([Snap Store][snap-store], or the [.snap file][linux-snap]).
+  For ARM64: [AppImage][linux-arm64-appimage], [.deb][linux-arm64-deb], [.rpm][linux-arm64-rpm].

-## Build from source
-
-```sh
-cargo run --release -p solidcraft -- --sample      # desktop app with a sample part
-cargo run --release -p solidcraft-cli -- commands  # the command registry
-cargo run --release -p solidcraft-cli -- run examples/bracket.json --out bracket.step
-cargo xtask ci                                     # fmt, clippy, tests, icons, assets, layers, wasm
-```
-
-More commands, the Windows cross-build and the browser build are in [docs/building.md](docs/building.md).
-
-## AI agents (MCP)
-
-`solidcraft-cli mcp` is a [Model Context Protocol](https://modelcontextprotocol.io) server. Headless it
-runs its own design session, or with `--connect` it drives the running app so you can watch.
-Claude Code: `claude mcp add solidcraft -- solidcraft-cli mcp`. If a terminal doesn't find
-`solidcraft-cli` (older Windows installers don't put it on `PATH`), give its full path (by default
-`"C:\\Program Files\\SolidCraft\\solidcraft-cli.exe"`). Tools, access rules and an example session:
-[docs/mcp.md](docs/mcp.md).
-
-## Scripts
-
-A script is a JSON list of the same commands the UI runs, executed with `solidcraft-cli run`.
-Format and example: [docs/scripts.md](docs/scripts.md). Pages can also be driven through the
-[browser command API](docs/browser-api.md).

+## What works
+
+- **Current-view DXF export** from File → Export Current View as DXF, with hidden edges
+  omitted or dashed, shown body placements and the current camera. See [view DXF](docs/view-dxf.md).
+
+- **Sketches** on origin planes, offset planes or planar faces: lines, rectangles, circles,
+  arcs, polygons, slots, ellipses, fit/control splines, conics and text; construction geometry,
+  projection, trimming, fillets and chamfers, including corners at the origin.
+  New face attachments retain supported construction identities and chosen occurrences;
+  missing sources expose an explicit plane repair workflow. See [face attachments](docs/face-attachments.md).
+  Explicitly closed fit splines and closed associative offsets use periodic C2 interpolation.
+  Supported convex line-and-arc offsets retain their identity when an inset consumes corner
+  arcs, and linked extrusions follow the current boundary. Breaking the association freezes
+  the boundary and keeps existing extrusions usable.
+  Curve drawing and picking adapt together to zoom and display scale, including small circles
+  at Fit and sketches in placed components.
+- **Constraints and dimensions** solved by our own solver. Points the constraints fix relative
+  to known geometry are placed exactly by construction (loci intersections and rigid-cluster
+  decomposition, after Owen 1991 and Fudos–Hoffmann 1997); Levenberg–Marquardt solves the rest,
+  and the rank of its Jacobian gives the remaining degrees of freedom. Constraints: coincident,
+  point on curve, horizontal/vertical, parallel, perpendicular, tangent, curvature (G2), equal,
+  concentric, collinear, midpoint, symmetry, fix; linear, aligned, horizontal, vertical,
+  point-to-line, radius, diameter, angle, arc sweep, arc length and slot length dimensions driven
+  by parameters. Over-constraining edits are rejected; fully constrained geometry turns black.
+  Dragging solves the sketch every frame and rebuilds the model once, when the drag ends.
+  Select a line or its two endpoints, type its dimension and press Enter to commit one undo
+  step; with Sketch Dimension it's D, click, type, Enter. Fit keeps sketch geometry clear of the palette and navigation controls.
+- **Profiles** found automatically, including regions split by lines and holes inside outlines.
+  Newly captured complete adaptive boundaries retain their outer and hole source identities
+  when spline span counts change. Partial or ambiguous boundaries do not qualify.
+- **Features** on a parametric timeline: extrude, revolve, sweep, loft, fillet/chamfer,
+  shell, draft, holes, threads, patterns, mirror, split, combine, move and construction geometry.
+  The timeline rebuilds incrementally; features can be edited, suppressed, renamed, reordered
+  and deleted. Supported geometry and current limitations are described in [ROADMAP.md](ROADMAP.md).
+  New revolves preserve symmetric and two-sided angular placement across reversed axes;
+  older designs retain their saved convention when reopened or edited.
+- **Parameters and configurations** with unit-aware expressions (`2 * width + 5 mm`,
+  `angle / 2`), ordered rules, feature suppression and per-row body materials/appearances.
+- **Assemblies** with nested components and occurrences, joints, motion studies, contact sets,
+  interference and material-aware mass properties. Recorded body transfers preserve modelling
+  history and world placement; 3D sketch wires retain their coordinate frames through edits.
+- **Sheet metal** with flanges, hems, fold/unfold/refold, material cutouts, flat patterns,
+  retained shallow prismatic pockets, exact line/arc/circle DXF outlines and bend tables;
+  plastic enclosure features and rules. Pocket depth and side survive unfold/refold and appear
+  separately from through-hole outlines in the flat preview and DXF.
+- **Files**: design containers (`.solidcraft`) with lossless binary mesh payloads;
+  plain JSON remains supported for opening, Save As and export. Desktop Open can show a saved
+  provisional picture from warm geometry caches while rebuilding before editing; caches never
+  replace the parametric design. Export to STEP (AP242 with body names, colours and
+  components as assemblies; revolved faces as native planes, cylinders, cones, spheres and tori),
+  IGES 5.3 (manifold solid B-reps with names and colours), 3MF, STL (binary/ASCII) and OBJ, and
+  assemblies with joints as URDF for robot simulators (docs/urdf.md);
+  3MF, STL, OBJ and glTF 2.0 (`.glb`/`.gltf`, its node tree as components and its materials as
+  appearances) import as mesh bodies (they render, measure, move and export; solid features
+  need B-rep bodies). The `mesh.convert` command reconstructs supported closed constant-section parts
+  as parametric solids with planar and circular cylindrical faces;
+  STEP import (AP203/AP214/AP242 solids, assemblies, units, names, colours) and IGES import
+  (manifold solid B-reps, or trimmed and bounded surfaces sewn into solids) as a base feature
+  that later features build on — open a `.step`/`.stp`/`.igs`/`.iges` file, insert one into a
+  design, or drop it on the window ([docs/step-import.md](docs/step-import.md)); FreeCAD
+  `.FCStd` and Rhino `.3dm` solids import the same way through
+  [cadmpeg](https://github.com/cadmpeg/cadmpeg) in the desktop app and CLI.
+- **Render:** opaque surfaces can use metal fraction, roughness and dielectric IOR in the
+  integrated product viewport and CPU preview PNGs. Existing simple colors remain supported.
+  Fixed direct lighting is a preview; HDRI, refraction and texture maps are not implemented.
+  See [opaque surfaces](docs/render-opaque-pbr.md).
+- **Display meshes** from our own tessellation planner: each face becomes a plan of (u, v)
+  points and triangles that shares its edge nodes with its neighbours, so the mesh is watertight.
+  Facets follow the chord tolerance, the facet angle and a longest side, with cells at most 2:1
+  along straight directions. Box-bounded and four-cornered faces mesh as structured grids.
+  Trimmed faces are cut into four-sided patches: squares around holes, butterflies in round
+  faces, motorcycle traces from concave corners (after Lyon et al. 2019). Each patch then meshes
+  as a Coons grid. Intersection edges are evaluated by Newton on both surfaces. A compute shader
+  evaluates the plans for the whole scene in one dispatch, with a CPU fallback when the GPU
+  can't build it. Planning and evaluating the 78 reference bodies takes about 65 ms, 50–65×
+  faster than the previous mesher.
+- **Desktop app** (egui + wgpu): toolbar with workspace tabs, browser, timeline, 3D viewport with
+  axis view and navigation bar, sketch tools, feature dialogs, command palette, and a JSON-lines
+  control channel so agents and tests can drive it.
+  Feature errors and Help can open an editable **Create Issue** draft with relevant context
+  and an optional reviewed screenshot; opening GitHub does not submit the report.
+- **Headless CLI** `solidcraft-cli`: run command scripts, measure (volume, area, centre of mass,
+  face/edge/vertex counts), export, render PNG snapshots and replay reference recipes.
+- **MCP server** `solidcraft-cli mcp`: AI agents model, measure and look at parts headless or
+  in the running app (see below).
+
+## Build and run
+
+```sh
+cargo run --release -p solidcraft -- --sample          # desktop app with a sample part
+cargo run --release -p solidcraft-cli -- commands      # the command registry
+cargo run --release -p solidcraft-cli -- run examples/bracket.json --out bracket.step

+cargo run --release -p solidcraft -- part.step          # open a STEP file as a new design
+cargo run --release -p solidcraft-cli -- eval part.step # measure an imported STEP file
+cargo xtask ci                                          # fmt, clippy, tests, icons, assets, layers, wasm
+```
+
+UI artwork changes follow the [icon specification](assets/icons/ui/STYLE_GUIDE.md).
+The [included review tool](assets/icons/ui/README.md) discovers new icons and keeps
+unaccepted artwork Open; run `cargo xtask icons` to check the collection.
+
+Windows builds: `cargo xwin build --release --target x86_64-pc-windows-msvc -p solidcraft`.
+
+On Windows, macOS and Linux, SolidCraft detects a connected 3D mouse through its HID multi-axis
+controller interface: a 3Dconnexion SpaceNavigator or SpaceMouse, or a homemade device that
+declares itself one. Move the cap to pan and zoom, and tilt or twist it to rotate the 3D view.
+While editing a sketch, the cap pans and zooms without changing the sketch view. The Navigation
+page in Preferences has an on/off switch, a speed control and, for each of the cap's six axes, an
+invert switch and a speed for the 3D mouse. The web app reads
+it too, through the browser; Firefox needs a 3DxWare setting first (see
+[Getting started › 3D mouse in the browser](docs/book/src/guide/getting-started.md#3d-mouse-in-the-browser)).
+
+With 3DxWare on Windows, SolidCraft follows 3DxWare's profile for it when there is one, and
+3DxWare's object mode (tilt to roll, twist to spin) until there is. The mouse-wheel turns that
+3DxWare makes from the cap's motion are ignored, so the view doesn't zoom in steps as the cap tilts.
+
+On Linux SolidCraft reads the 3D mouse through `spacenavd` when that daemon runs (its socket
+`/var/run/spnav.sock`), so what you set in `spnavcfg` (swapped or inverted axes, sensitivity, dead
+zones) applies as it does in other programs, and no udev rule is needed. With nothing set there,
+the motion is the same as without the daemon. Without `spacenavd`, SolidCraft reads `/dev/hidrawN`
+directly, so the logged-in user needs access to the device. A udev rule that adds the `uaccess`
+tag does that, for example
+`/etc/udev/rules.d/70-3d-mouse.rules` for USB devices with 3Dconnexion's vendor id, and for its
+Bluetooth ones (where `idVendor` isn't set, so the HID id is matched instead):
+
+```
+SUBSYSTEM=="hidraw", ATTRS{idVendor}=="256f", TAG+="uaccess"
+SUBSYSTEM=="hidraw", KERNELS=="0005:256F:*", TAG+="uaccess"
+```
+
+Older SpaceNavigators use Logitech's vendor id `046d`, so add a rule with their product id (see
+`lsusb`) instead of matching every Logitech device. A homemade device needs a rule with its own
+vendor and product id. Reload with `sudo udevadm control --reload && sudo udevadm trigger`, then
+replug the device. The Flatpak sandbox does not expose hidraw devices, so the 3D mouse only works
+with native builds there for now.
+
+SolidCraft finds the axes from the device's report descriptor, so it doesn't matter how a device
+lays them out: translation and rotation in separate reports (3Dconnexion's wired devices), all six
+in one (its wireless ones and most homemade devices), after the buttons, or narrower than 16 bits.
+Each axis is scaled from the range the descriptor declares.
+
+On macOS SolidCraft talks to the 3Dconnexion driver (3DxWare) when it is installed, through the
+driver's client API (`crates/threedx-client`; the framework is loaded at run time, never bundled).
+The driver keeps the device to itself, and sends it only to a program it can identify: SolidCraft
+as an `.app` (the packaged app). Without the driver, or with its helper not running, SolidCraft reads the device through IOKit like on Windows.
+
+SolidCraft does not follow 3DxWare's profile on macOS. Its default is 3DxWare's object mode.
+
+In the browser: `cd apps/solidcraft-web && trunk build --release --public-url ./` (WebGPU, or
+WebGL2 with `?webgl`; `?sample` opens the sample part).
+
+Agents can control the document open in a browser tab through `window.solidcraft.execute(...)`
+and `window.solidcraft.request(...)`; see the [browser command API](docs/browser-api.md).
+
+## Scripts
+
+A script is a JSON list of commands, the same ones the UI runs:
+
+```json
+{"commands": [
+  {"command": "sketch.create", "params": {"plane": "XY"}},
+  {"command": "sketch.rectangle.two_point", "params": {"p0": [0, 0], "p1": [40, 30]}},
+  {"command": "solid.extrude", "params": {"distance": 20}},
+  {"command": "solid.fillet", "params": {"edges": [[0, 0, 10]], "radius": 3}}
+]}
+```
+
+## AI agents (MCP)
+
+`solidcraft-cli mcp` is a [Model Context Protocol](https://modelcontextprotocol.io) server on
+stdio. Headless it runs its own design session; with `--connect 127.0.0.1:PORT` it drives the app
+started with `solidcraft --control PORT`, so you can watch the agent model. Tools:
+`list_commands`, `execute`, `batch`, `inspect_design`, `measure`, `body_topology`,
+`set_parameter`, `screenshot` (returns the image), `export`, `crash_reports`, `undo`, `redo`,
+`new_design`, `open`, `save`. Tool calls reach files only in the open design's folder (when it lies inside your home
+folder, never home itself or a hidden folder), SolidCraft's recovery folder and folders given with
+`--allow-path DIR`. Claude Code: `claude mcp add solidcraft -- solidcraft-cli mcp`. Details, client
+configuration and an example session: [docs/mcp.md](docs/mcp.md).

 # SolidCraft roadmap
 
-The short version, for people who use SolidCraft. The detailed developer status (milestone
-tables, limitations, measurements) is in [docs/roadmap-detail.md](docs/roadmap-detail.md).
-
-## What SolidCraft is
-
-SolidCraft is open-source parametric 3D CAD written in Rust. You sketch, constrain, extrude, and
-change a parameter to watch the timeline rebuild. It runs as a desktop app and in the browser
-([try it](https://solidcraft.io/app)), and it has a command-line tool and an MCP server so that
-scripts and AI agents can drive the same commands you use.
-
-## Works today
-
-- Sketching with a constraint solver, and the usual create and modify tools.
-- Extrude, revolve, loft, sweep, coil, fillet, chamfer, shell, draft, holes, threads,
-  patterns, mirror and split.
-- Parameters with units and expressions, and configurations.
-- Faces and edges keep their names through edits, so references survive changes.
-- Components, assemblies, joints, motion studies and exploded views.
-- Sheet metal with flat patterns and DXF export, and a plastic-enclosure subset.
-- A Render workspace with GPU rendering, studio lighting, materials and image export
-  (first release in 0.22.0).
-- Import and export of STEP, IGES, 3MF, STL, OBJ and DXF, and FreeCAD and Rhino files.
-- Autosave and crash recovery, and the browser build of the same app.
-
-The full list of commands is in [docs/features.md](docs/features.md). Release notes for each
-version are on the [releases page](https://github.com/tangency-labs/solidcraft/releases).
-
-## In progress now
-
-Each feature below is a [milestone](https://github.com/tangency-labs/solidcraft/milestones) holding
-the issues for it, so the count shows how far along it is. Counts are as of 2026-10-25, one per
-feature or request. Work merged on a feature branch (`drawings`, `render`) counts as built but
-reaches the app only when that branch merges. They are rough, not a promise.
-
-- **[Rendering & materials](https://github.com/tangency-labs/solidcraft/milestone/17)**: in progress, 9 of 34 pieces done, 3 of them built only on the `render` branch and in the app when it merges. The basic Render workspace is already in releases (0.22.0); the interface rework (#6281) and the material and light libraries are what is left.
-- **[Drawings](https://github.com/tangency-labs/solidcraft/milestone/8)**: in progress, 3 of 21 pieces built (2 in releases, 1 on the `drawings` branch), and 3 more partly built there (sheets and borders, bill-of-materials types, the paper scene). Not in the app yet: it lands when the `drawings` branch merges. Today you can export the current view as a DXF.
-- **[Sheet metal](https://github.com/tangency-labs/solidcraft/milestone/15)**: in progress, 1 of 30 requests done. Flanges, hems, unfold and flat patterns already work; the 30 are extensions, mostly the per-edge flange options (segments, miters, partial flanges, reliefs) and bend allowance.
-- **[Sketching](https://github.com/tangency-labs/solidcraft/milestone/14)**: in progress, 12 of 50 pieces done. Dimension types, selection and snapping options.
-- **[Solid modeling](https://github.com/tangency-labs/solidcraft/milestone/2)**: in progress, 9 of 50 pieces done. Blends, holes, threads and patterns.
-- **[Assemblies & joints](https://github.com/tangency-labs/solidcraft/milestone/3)**: in progress, 4 of 19 pieces done. Joints, motion studies and exploded views already work; placement rules, linked sub-assemblies, fastener stacks and weldment corners are the pieces left.
-- **[Import & export](https://github.com/tangency-labs/solidcraft/milestone/5)**: in progress, 7 of 39 pieces done. FreeCAD, SolidWorks and point-cloud import, and mesh export options.
-- **[AI agents & MCP](https://github.com/tangency-labs/solidcraft/milestone/18)**: in progress, 2 of 8 pieces done. Agent chat and the MCP server.
-- **[Interface, web app & plugins](https://github.com/tangency-labs/solidcraft/milestone/4)**: in progress, 31 of 96 pieces done. Ribbon redesign, navigation, themes, the web app and plugins.
-- **[SMLib kernel migration](https://github.com/tangency-labs/solidcraft/milestone/1)**: in progress, 1 tracking issue open. The kernel is moving from truck to NVIDIA's SMLib (usd-brep, Apache-2.0) on the `kernel-smlib` branch; it is not in releases yet. Tracked in [#4012](https://github.com/tangency-labs/solidcraft/issues/4012).
-
-## Next
-
-- **[Surfacing](https://github.com/tangency-labs/solidcraft/milestone/16)**: next, 6 of 14 pieces done. Patch, trim, blend and match exist; the rest of the surface toolset is planned.
-- **[Manufacturing / CAM](https://github.com/tangency-labs/solidcraft/milestone/9)**: next, 1 pieces tracked, none done. There is no CAM in SolidCraft yet. Send to Slicer and a first toolpath slice are in review; proposals are [#1153](https://github.com/tangency-labs/solidcraft/issues/1153) and [#1621](https://github.com/tangency-labs/solidcraft/issues/1621).
-
-Features are not tied to a release or a date. Work lands in the daily releases as it is finished.
-Anything without a milestone, such as bug fixes, is not a feature and is not listed here.
-
-## How releases work
-
-- Releases ship daily, as numbered versions (v0.22.0, v0.22.1) with nightly pre-releases in
-  between. They are delivered through the in-app updater.
-- SolidCraft tells you when a newer stable release exists and never updates without asking.
-  Where it can replace itself safely (AppImage, Windows installer and portable builds) there is
-  an **Update now** button; downloads are checked against the release's SHA-256 list. See
-  [updates and privacy](docs/book/src/guide/updates.md).
-- Design files carry a format number. A new version opens designs from older versions, but an
-  older version refuses a design saved by a newer one (0.22.0 writes format 35, and 0.21.0 and
-  earlier will not open it). Each release's notes say when the format changed. Keep a copy of
-  an important design before you move to a new version.
-
-## Licence
-
-SolidCraft is licensed MIT OR Apache-2.0, at your option; see [LICENSE-MIT](LICENSE-MIT) and
-[LICENSE-APACHE](LICENSE-APACHE). Versions already released stay available under those licences
-permanently.

-//! Bringing the window forward when a close stops at "save changes?".
-//!
-//! A close from the taskbar or a window switcher reaches the window while another app has the
-//! focus. The prompt it opens is only seen once the window comes forward, so the window asks for
-//! the focus then. A window the user is already in is left alone.
-//!
-//! winit's Focus asks as an application, which a window manager with focus-stealing prevention
-//! (KWin's default) refuses for a window used before the switch away: it only marks the taskbar
-//! entry. On X11 the request is sent again with the source EWMH gives "direct user actions"
-//! (`_NET_ACTIVE_WINDOW`, source 2), which is what this is: the prompt is the rest of the user's
-//! close. Native Wayland has no way for a window to raise itself, so there the attention request
-//! (xdg-activation) lets the compositor raise it or mark its taskbar entry.
-//!
-//! When: not at once. KWin raises the window, then the taskbar's closing context menu hands the
-//! focus back to the app that had it, a few milliseconds later, and the window would flicker
-//! forward and back. So the window asks once the menu is gone, `FIRST_AFTER` the close. It asks
-//! again only if the focus is taken back right after it came (a slow menu) or never came; a later
-//! switch is the user's own, and the window stays where the user put it.

-//! macOS: what a crash in native code leaves behind (docs/crash-reports.md).
-//!
-//! A crash inside a graphics driver or another library (a segfault, an `abort()`, a stack
-//! overflow) is no Rust panic: the panic hook never runs and the next start only found "an
-//! unclean exit". A signal handler for SIGSEGV, SIGBUS, SIGILL, SIGFPE, SIGTRAP (how a trap
-//! instruction arrives on Apple silicon) and SIGABRT now writes, before the process goes, the
-//! same small JSON file as the Windows filter (`native_crash.rs`): the signal, the faulting
-//! module and the offset into it, and a short frame-pointer walk, next to the run's crash journal
-//! (`solidcraft_engine::crash::native_paths`). The next start puts it into the unclean exit's
-//! report. The signal then goes on to the handler that was there before (the standard library's
-//! stack overflow message) or to the default action, so the process still dies of it and macOS
-//! still writes its own crash report (`~/Library/Logs/DiagnosticReports`; the file names the
-//! `pid` the JSON records).
-//!
-//! Installing a signal handler and asking dyld which image holds an address have no safe API,
-//! hence the `unsafe_code` allowance on this module (the app crate denies it). The handler runs
-//! on a thread that may have a broken heap, or on the small alternate stack after a stack
-//! overflow: it doesn't allocate, formats into a buffer on the stack, and only reads memory on
-//! the thread's own stack. It writes what it knows from the signal first and only then calls
-//! `dladdr` (not on POSIX's async-signal-safe list; it takes dyld's recursive reader lock and
-//! doesn't allocate) to name the modules, rewriting the file, so a hang or a fault in there
-//! still leaves a record.

-//! Windows: finding 3D mice without asking any other device anything (#2614).
-//!
-//! hidapi's enumeration opens every HID interface and reads its serial number, manufacturer and
-//! product strings: on USB, three control requests to every keyboard, mouse and touchscreen. The
-//! reader repeated it every two seconds while no 3D mouse was plugged in, and on some machines the
-//! keyboard then kept dropping off the bus and the cursor jumped. Plug and Play already names each
-//! interface's top-level usage in its hardware IDs (`HID_DEVICE_UP:0001_U:0008`: Generic Desktop,
-//! Multi-Axis Controller), so the reader asks it, which sends nothing to any device, and opens only
-//! the interfaces that are 3D mice.
-//!
-//! The configuration manager has no safe API, hence the `unsafe_code` allowance on this module
-//! (the app crate denies it; see `native_crash.rs`).
